Seagate releases a duo of thin, high-density mobile hard drives

Seagate has announced tiny new mobile hard disk drives that boast high density in a seven-millimeter-thick form factor. The company expects the new drives will make high-capacity drives a good option for more classes of mobile PCs like thin laptops. 

Seagate claims it has achieved an industry-best areal density of 1TB per platter in the 2.5" form factor, which it's used to create 1TB and 2TB drives. Each model weighs in at 0.198 pounds. In keeping with the diminuitive theme, the 2TB model consumes 0.5 W at idle and 1.7 W during seeks. The 1TB model consumes marginally less. Both drives come with 128MB of cache.

Seagate will offer versions of these drives with self-encrypting drive and FIPS 140-2 support, including a built-in random number generator. Some will also include what Seagate calls "Instant Secure Erase" technology to quickly wipe data.

There's no word yet on pricing, but the drives' product page suggests we can expect competitive cost-per-gigabyte ratios. Each model comes with a two-year limited warranty.
